HPCC-9572 - Fix hash dedup row leak after spill event

When hash dedup spills, it continues to use the bucket hash tables
for dedupping purposes. The memory manager callback to flush
the HT was not protected by a mutex, which meant the reset could
overlap with another thread adding new rows, causing the flush to
in effect lose those newly added rows.

Also, close all bucket spill streams at end of phase (instead of
waiting for each new level to start). Minor significance, but the
output streams will have some buffered rows, and it is better to
close and flush those out upfront, rather than leave them in memory
whilst the other phases are being handled.

HPCC-9628 Eclcc hangs at end if libarchive dynamically unloaded

In my tests setup, I have the libs directory on my plugins path, meaning that
eclcc will try to load libarchive as a plugin, then unload it when it finds it
is not.

This means that MODEXIT gets called before removeFileHook (due to bugs in the
modexit logic - it should really only be called on the last unload, not on any
unload).

Protect against that event by setting lock ptr to NULL.

HPCC-9634 Uninitialized members of ThorDataLinkMetaInfo

If a splitter has a null input (because pruned) the null input
implementation had uninitialized ThorDataLinkMetaInfo members.
I don't think any were of consequence, the critical members
totalRowsMin/Max were initialized.
